Datasheet Summary
Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
1.0 Features
No-load power consumption < 30mW at 230VAC along with fast dynamic load response and short turn-on delay in typical 5V2.4A 12W pact adapter/charger applications
Tight constant-voltage and constant current regulation across line and load range
Primary-side feedback eliminates opto-isolators and simpli es design
Intelligent low power management achieves ultra-low operating current 250 A at no-load
Proprietary optimized 89kHz maximum PWM switching frequency with quasi-resonant operation achieves best size ef ciency and mon mode noise ser-con gurable 5-level cable drop pensation provides design...
